How to perform a search for relatives of a deceased person for genealogical research?

I am building a family tree and hit a dead end. How do I legally access death certificates or probate records to find living descendants or siblings of someone who passed away in the early 2000s?

To find relatives of a deceased person, start by searching digitized Social Security Death Index (SSDI) records or local probate court filings. Probate files are particularly useful because they legally list heirs-at-law and living descendants.
